A converging-diverging nozzle has an area ratio of 5.9. (1) Determine the (P0/Pt) values corresponding to the 1st, 2nd, and 3rd
critical points, where Pt is the chamber total pressure and P0 is the ambient pressure.
1 answer:
Answer:
Check the explanation
Explanation:
The Total pressure is the overall of fixed or static pressure p, the dynamic pressure q, as well as gravitational head. Total pressure can also be referred to as the measure of the overall energy of the airstream, and is the same to static pressure plus velocity pressure.

Answer:
C
Explanation:
Pitot tube:
Pitot tube is a device which is used to measure the velocity of flow by measuring pressure difference between the points.
As we know that stagnation pressure is the summation of dynamic and static pressure.
Stagnation pressure = Static pressure + Dynamic pressure
So
Dynamic pressure = Stagnation pressure - Static pressure
We know that dynamic pressure
On the other hand Pitot tube measure the dynamic pressure.
So option C is correct.
